Research on China Imaging Altimeter Planning Problem for Area Target Observation

The China Imaging Altimeter (CIALT) mission planning problem has complexity constraints. Overlap observation play a role in area target observation. Based on the analysis, the space gird was constructed. A calculation method for coverage percentage based on grid space statistic is proposed. A mathematical model of mission planning is established. A solving method combines constraint propagation algorithm and greedy algorithm is proposed. An area target mission with one month’s observation period was planned. The results showed that the method realized the goal that maximizing area target coverage in the shortest possible time and form the unique planning results at same observation requirements. It is applicable to CIALT area target observation planning.
